Product details
Overview
MAX6070BAUT25/V+T from Analog Devices is a precision 2.5V series voltage reference IC in 6-pin SOT23 package, delivering ±0.04% initial accuracy, 6ppm/°C max temperature drift (A grade), 4.8µVP-P (0.1Hz–10Hz) low-frequency noise, and ±10mA sourcing/sinking capability - enabling high-accuracy ADC/DAC biasing in industrial process control systems.
For engineers reviewing the MAX6070BAUT25/V+T datasheet, MAX6070BAUT25/V+T pinout, MAX6070BAUT25/V+T application, or MAX6070BAUT25/V+T equivalent, this page provides verified electrical specifications, thermal performance data across –40°C to +125°C, filter-enabled wideband noise suppression, and AEC-Q100-qualified alternatives for automotive-grade designs.
Technical Context
The MAX6070BAUT25/V+T implements a bandgap-based series reference architecture with dual-output force-sense topology (OUTF/OUTS) and integrated noise-filter input (FILTER pin), supporting stable 2.5V output under load currents from –10mA to +10mA with dropout as low as 110mV at 10mA.
It features enable-controlled shutdown (6µA ISD), 84dB 60Hz ripple rejection, and capacitive-load stability up to 10µF - optimized for high-resolution data acquisition where long-term drift (<40ppm over 1000h) and thermal hysteresis (85ppm) directly impact system calibration integrity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Voltage | 2.500V ±0.04% at +25°C - enables direct interface with 2.5V ADC references without scaling. |
| Temp Drift (max) | 6ppm/°C (A grade) - ensures ≤±0.015% output variation over –40°C to +125°C industrial range. |
| 1/f Noise | 4.8µVP-P (0.1Hz–10Hz) - critical for sub-18-bit ADC accuracy in precision instrumentation. |
| Supply Current | 150µA typical - supports ultra-low-power sensor nodes and battery-backed measurement systems. |
| Load Current | ±10mA sourcing/sinking - drives 10kΩ DAC reference loads or multiple op-amp bias networks. |
| Dropout Voltage | 110mV min at 10mA - allows operation from 2.8V supply, compatible with Li-ion single-cell systems. |
| Ripple Rejection | 84dB at 60Hz - suppresses power-supply coupling in AC-powered industrial controllers. |
Pinout & Package
Package: 6-pin SOT23 (U6+5/U6+5A outline), 2.9mm × 1.6mm footprint, JEDEC-compliant, RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - FILTER | Noise filter input | Accepts 0.1µF capacitor to ground; reduces high-frequency noise when enabled - unique to MAX6070 variant. |
| 2 - GNDF | Ground force | Provides dedicated ground return path for internal bandgap core - improves PSRR and noise immunity. |
| 3 - EN | Enable control | Logic-high (>0.7×VIN) enables output; logic-low disables with 6µA shutdown current. |
| 4 - IN | Supply input | Operates from 2.8V to 5.5V; requires ≥0.1µF bypass capacitor near pin for stability. |
| 5 - OUTS | Sense output | Connects to load ground point; enables Kelvin sensing to eliminate PCB trace IR drop error. |
| 6 - OUTF | Force output | Delivers regulated 2.5V; must be shorted to OUTS near load to maintain <0.01% regulation accuracy. |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar voltage reference applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX6071BAUT25/V+T | Same 2.5V output, no FILTER pin; lower 3.6µVP-P 1/f noise but no high-frequency filtering option. | Lacks noise-filter capability - unsuitable for wideband RF or switching-power-supply-adjacent designs. | Select when lowest possible 0.1–10Hz noise is prioritized and external filtering is handled elsewhere. |
| ADR4525BRZ | 2.5V reference with 2ppm/°C max drift, 1.8µVP-P noise, but 4.5mA quiescent current and SOIC-8 package. | Higher power and larger footprint - incompatible with space-constrained portable or automotive modules. | Choose only when ultra-low drift (<2ppm/°C) justifies 30× higher supply current and board area penalty. |
Compared with MAX6071BAUT25/V+T, the MAX6070BAUT25/V+T trades slightly higher base noise for design flexibility via the FILTER pin; versus ADR4525BRZ, it delivers 97% lower supply current and 60% smaller footprint while maintaining AEC-Q100 compliance for automotive use.

FAQ
What is the maximum operating temperature for MAX6070BAUT25/V+T?
The MAX6070BAUT25/V+T is specified over the extended industrial temperature range of –40°C to +125°C, with junction temperature rated to +150°C. Its 6ppm/°C max drift and 40ppm long-term stability are guaranteed across this full range, making it suitable for under-hood automotive and factory-floor industrial deployments where ambient heat exceeds 100°C.
Does MAX6070BAUT25/V+T require an external capacitor on the FILTER pin?
The FILTER pin on MAX6070BAUT25/V+T is optional: connect a 0.1µF capacitor to ground only when suppressing high-frequency noise (e.g., in switch-mode power supply environments); leave unconnected for standard low-noise operation. This flexibility distinguishes MAX6070BAUT25/V+T from the MAX6071 variant, which lacks this pin entirely.
How does the force-sense (OUTF/OUTS) topology improve accuracy in MAX6070BAUT25/V+T?
The MAX6070BAUT25/V+T uses separate force (OUTF) and sense (OUTS) outputs to eliminate voltage drop errors caused by PCB trace resistance between the IC and load. By routing OUTS directly to the load ground point and shorting OUTF to OUTS near the load, the device maintains ±0.01% regulation accuracy even with ±10mA load current and 100mΩ trace resistance - critical for 24-bit ADC systems.
Is MAX6070BAUT25/V+T AEC-Q100 qualified?
Yes, MAX6070BAUT25/V+T is AEC-Q100 qualified (Grade 1: –40°C to +125°C), with test reports covering HTOL, TCT, ESD, and AC/DC parametric validation. This qualification confirms suitability for automotive applications including engine control units, battery monitors, and ADAS sensor signal conditioning - unlike non-qualified references that lack stress-test documentation.
What is the minimum input voltage required for MAX6070BAUT25/V+T to regulate at 2.5V?
The MAX6070BAUT25/V+T requires a minimum input-to-output differential of 110mV at 10mA load (per datasheet Note 3), meaning VIN must be ≥2.61V to maintain 2.5V output regulation. At lighter loads, dropout falls further - e.g., 80mV at 1mA - enabling operation from 2.8V supplies common in single-cell Li-ion and energy-harvesting systems.
